Thus not only will thefeeder as an entirety conform to the irregularities in the pile ofstock, but any unevenness in the articles composing the pile can becompensated for by the greater or less adjustment of one side of theblock.

While I do not restrict myself to any special means for operating thefeeder, yet I have shown it in Fig. 1 as being located on a feedtable I,the rod a being extended through a hollow guide 75 and adj ustablysecured at its outer end to a sleeve carried by a reciproeating carriage25 I claim as my invention- 1. A feeder comprising alongitudinallymovable rod, a head mounted on said rod so as to moveaxially thereon, and having an upper, forward edge forminga shoulder,means for adjusting said head perpendicularly to said rod and a block onthe forward end of said head having its inner edge adjacent to saidshoulder and tapered on its upper surface toward its outer edge, andmeans for adjusting said block relatively to said shoulder,substantially as set forth.

2. A feeder comprising a longitudinallymovable rod, a head mounted onsaid rod so as to move axially thereon and having an upper forward edgeforming a shoulder, a block on the forward end of said head extended inadvance of said shoulder and having its upper surface tapered, a springinterposed between said head and block exerting an upward pressure onthe latter, and means for adjusting said block at its sides,substantially as set forth.

3. A feeder. comprising a longitudinallymovable rod, a head mounted onsaid rod so as to move axially thereon and having a forward edge, meansfor adjusting said head perpendicularly to said rod, a block on theforward end of said head extended in advance thereof and having itsupper surface inclined, and means engaging the sides of said block 'foradjusting and holding the same relative to the forward edge of saidhead, substantially as set forth. 4;. A feeder comprisingalongitudinallymovable rod, a sleeve loose on said rod so as to moveaxially thereon, a head from which said sleeve extends having an upperforward edge forming a shoulder, a block on said head having an upperinclined surface, said block being extended in advance of said head, aspring interposed between said head and block exerting an upwardpressure on the latter, and screws carried by said block at its sidesfor adjusting said block bodily or at either side, as set forth.

5. A feeder comprising a longitudinallymovable rod, a sleeve loose onsaid rod and having a bifurcated end, a head adjustably held to saidbifurcated end and havinga forward edge forming a shoulder, and a blockon said head capable of being raised and lowered thereon, substantiallyas and for the purpose stated. 1

6. The combination with the rod, of the head mounted on said rod havingforward grooved ends and an upper forward edge forming a shoulder,-ablock having its upper surface inclined and formed with a longitudinalrecess to accommodate said head, a spring between said head and blockbearing up? wardly on the latter, and screws carried by said block atits sides and engaging said head, whereby the block may be adjustedbodily or at either side, substantially as set forth.

7. The combination with the rod, of a sleeve swiveled thereon having abifurcated end, a head havinga lip, and a screw adjustably holding saidlip within said bifurcated end, a block fitted on said head so as to bemoved up and down thereon, said block having its,upper surface inclined,a spring fitting in a recess of said block and bearing at one endagainst a shoulderof said head, and screws carried by said block andengaging saidhead for adjusting the former, substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
